I'm interested in the area around the lunar north pole, from 88N to the pole. I'd like to have 3D images of that area, but I've been unable to find a program that will read the LOLA data files. I've tried several 3D mapping programs, and I've had no success.

Is there a method to generate 3D images, or are there such files available for this area of the moon?

Thanks,

JR

that is NORMAL the LOLA data is laser points .Only about 10% of the moon is covered so the rest is interpreted using a spline fit
If you search here and over at Shatters.net( celestia site) i did a LOT of reprocessing of the laser points

the LRO WAC-DTM stereo topographic is much better

I use the LRO data set now

I've started studying gimp and its library of functions and am planing on finding the edges,

DO NOT !!!!! use gimp on 16 bit data !!!!!!!!!!!!!!!!!!!

gimp is 8 bit ONLY !!!!! you will kill all the information in the 16 bit gray images
8 big gray = 256 tones ( gimp )
16 bit = 65538 tones
also the LOLA data is in 16 bit SINGED LSB format
-32767 to 32768

if you must there is a 32 bit program ( gimp plugin is 8 bit ONLY) called G'mic
http://gmic.sourceforge.net/index.shtml
the TERMINAL version is 32 bit
the gimp plugin is 8 bit ONLY

the terminal is what i used to reprocess the laser point data after importing the PDS data using ISIS3
